[0398]Preparation of Optical Film

[0399]As shown below, optical film samples 1 to 43 and 54 to 66 were prepared by the antistatic hard coat layer forming composition (coating solution) being prepared and the antistatic hard coat layer (referred to below as “hard coat layer”) being formed on the transparent base material.

[0400]Synthesis of Ion-Conducting Compound (Conductive Polymer) (a) IP-15

[0401]As a compound corresponding to (A-2) in JP4600605B, IP-15 (30 mass % of ethanol solution) which was a quaternary ammonium salt-containing polymer which has an ethylene oxide chain was synthesized in the same manner as the synthesis example 2 in the patent document. The weight average molecular weight measured using GPC was approximately 200,000.

[0402]Synthesis of Ion-Conducting Compound (a) IP-16

[0403]As a compound corresponding to (A-5) in JP4678451B, IP-16 (30 mass % of ethanol solution) which was a quaternary ammonium salt-containing polymer which has an ethylene oxide chain was synthesi...

[0508]Preparation of Hollow Silica Dispersion Solution B-1

[0509]With regard to 500 parts of the hollow silica dispersion solution A-1 which is prepared in example 1, after 15 parts of acryloyloxy propyl trimethoxysilane and 1.5 parts of di-isopropoxy aluminum ethyl acetate were added and mixed, 9 parts of ion-exchanged water was added. The mixture was cooled to room temperature after reacting for 8 hours at 60° C. and 1.8 parts of acetyl acetone was added. While MI BK (methyl isobutyl ketone) was added so that the total solution amount is substantially uniform, the solvent was replaced using evaporation at reduced pressure. Finally, a dispersion solution B-1 was prepared by adjusting so that the solid content is 20%.

[0510]Preparation of Hollow Silica Dispersion Solution A-2

[0511]A hollow silica particle dispersion solution A-2 (solid content concentration of 18.2 mass %) where the average particle diameter was 50 nm, the shell thickness was 8 nm, and the refractive index of the sili...

Abstract

Providing is an antistatic hard-coat-layer forming composition including a nonvolatile component containing a conductive polymer (a) a compound (b) and a photo-polymerization initiator (c); and a volatile component containing a solvent (d) having a hydroxyl group, and a solvent (e) having no hydroxyl group where the boiling point is 120° C. or less, wherein the solvent (d) contains a solvent (d2) with 4 or more carbon atoms having a hydroxyl group where the boiling point is 90° C. or more and the SP value is 22.0 to 35.0, the proportion of the polymer (a) in the nonvolatile component is 1 to 20 mass %, the proportion of the solvent (d) in the volatile component is 0.5 to 25 mass %, and the proportion of the component (d2) in the component (d) is 80 to 100 mass %.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an antistatic hard coat layer forming composition, an optical film, an optical film manufacturing method, a polarization plate, and an image display device.[0003]2. Description of the Related Art[0004]In an image display device such as a cathode ray tube (CRT) display device, a plasma display panel (PDP), an electroluminescent display (ELD), a vacuum fluorescent display (VFD), a field emission display (FED), and a liquid crystal display (LCD), it is appropriate to provide an optical film which has antistatic properties and hard coating properties in order to prevent a reduction in visual recognition due to scratching or the attachment of dust or the like on a display surface.[0005]In order to obtain an optical film which has antistatic properties and hard coating properties, the forming of an antistatic hard coat layer using a coating composition, which contains a compound (for example, ...
